CollectionAdd::execute — Execute the statement
The execute method is required to send the CRUD operation request to the MySQL server.
此函数没有参数。
A Result object that can be used to verify the status of the operation, such as the number of affected rows.
Example #1 mysql_xdevapi\CollectionAdd::execute() example
<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();
$schema = $session->getSchema("addressbook");
$create = $schema->createCollection("people");
$collection = $schema->getCollection("people");
// Add two documents
$collection
->add('{"name": "Fred", "age": 21, "job": "Construction"}')
->execute();
$collection
->add('{"name": "Wilma", "age": 23, "job": "Teacher"}')
->execute();
// Add two documents using a single JSON object
$result = $collection
->add(
'{"name": "Bernie",
"jobs": [{"title":"Cat Herder","Salary":42000}, {"title":"Father","Salary":0}],
"hobbies": ["Sports","Making cupcakes"]}',
'{"name": "Jane",
"jobs": [{"title":"Scientist","Salary":18000}, {"title":"Mother","Salary":0}],
"hobbies": ["Walking","Making pies"]}')
->execute();
// Fetch a list of generated ID's from the last add()
$ids = $result->getGeneratedIds();
print_r($ids);
?>
以上例程的输出类似于：
Array
(
[0] => 00005b6b53610000000000000056
[1] => 00005b6b53610000000000000057
)
